Answer:
1. (22 + 19b) + 7 = 19b + 29
2. 18 + (5 + 6m) = 6m + 23
3. 11s (4) = 44s
4. 10y (7) = 70y
Explanation:
Always simplify your answer. First, rearrange the terms. (22 + 19b) + 7 / (19b + 22) + 7 / Second, eliminate the redundant parentheses. (19b + 22) + 7 / 19b + 22 + 7 / Third, add the numbers. 19b + 22 + 7 / 19b + 29 / And finally, you have your soultion, 19b + 29! I really hope this helped you. I am sorry if I possibly got one of the answers wrong, hope it helps! :)
